2015-04-22build: fix potential factor build failure on arm and mipsPádraig Brady
* src/longlong.h: Sync with the latest longlong.h from libgmp to: - Use __builtin_c[lt]zl on arm64. - Fix sparc64 vis3 build failure due to missing __clz_tab. - Avoid a clang build issue on mips. - Support thumb2 arm 32 bit system. * src/cfg.mk (sc_ensure_comma_after_id_est): Exclude longlong.h to ease merges.
2015-01-31doc,maint: fix use of "i.e." in documentation and commentsBernhard Voelker
To align with all other places (and correct grammar), change all upper-case "I.E." to "I.e.". Furthermore, ensure that "i.e." is followed by a comma. Finally, ensure to use a double-space before "I.e.," at the beginning of a sentence. The following was used to change all offending uses (apart from old ChangeLog files): $ git grep -liF 'i.e.' \ | xargs sed -i \ -e 's/I\.E\./I.e./g' \ -e 's/\. \(I\.e\.\)/. \1/g' \ -e 's/\([Ii]\.e\.\)\( \)/\1,\2/g' \ -e 's/\([Ii]\.e\.\)$/\1,/g' * cfg.mk (sc_prohibit_uppercase_id_est): Add new rule. (sc_ensure_double_space_after_dot_before_id_est): Likewise. (sc_ensure_comma_after_id_est): Likewise. (old_NEWS_hash): Refresh hash via "make update-NEWS-hash". * NEWS: Change use of "id est" abbreviation via the above command. * README: Likewise. * README-prereq: Likewise. * doc/coreutils.texi: Likewise. * gl/lib/rand-isaac.c: Likewise. * gl/lib/tempname.c.diff: Likewise. * man/stdbuf.x: Likewise. * src/cat.c: Likewise. * src/copy.c: Likewise. * src/copy.h: Likewise. * src/cp.c: Likewise. * src/cut.c: Likewise. * src/dd.c: Likewise. * src/df.c: Likewise. * src/fiemap.h: Likewise. * src/longlong.h: Likewise. * src/ls.c: Likewise. * src/numfmt.c: Likewise. * src/pr.c: Likewise. * src/shred.c: Likewise. * src/shuf.c: Likewise. * src/split.c: Likewise. * tests/Coreutils.pm: Likewise. * tests/df/df-symlink.sh: Likewise. * tests/df/skip-rootfs.sh: Likewise. * tests/init.sh: Likewise. * tests/ls/color-norm.sh: Likewise. * tests/misc/basename.pl: Likewise. * tests/misc/ls-misc.pl: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/shred-exact.sh: Likewise. * tests/misc/sort.pl: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/misc/tac-continue.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/tail-2/symlink.sh: Likewise.
2015-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.
2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2013-11-29build: fix potential factor build failure on arm and powerpcPádraig Brady
* src/longlong.h: Sync with the latest longlong.h from libgmp to: - avoid arm asm when being compiled for the thumb instruction [sub]set - avoid old powerpc assembly that is incompatible with newer GCC - add arm64 optimized count_trailing_zeros() - add sparc64 optimized add_ssaaaa() and umul_ppmm()
2013-03-04build: fix factor build failure on aarch64Torbjörn Granlund
* src/longlong.h (__aarch64__): Make add_ssaaaa and sub_ddmmss work. * NEWS: Mention the build fix. Reported at https://bugzilla.redhat.com/917735
2013-01-07factor: apply a more general fix to enable correct assemblyPádraig Brady
In addition to the previous 64 bit guards we've placed in longlong.h there are additional _LP64 guards required for mips with -mcpu >= 3, to avoid a build failure (http://bugs.gnu.org/13353) and on sparc with -mcpu >= v9 in 32 bit mode where for example, `factor 2123123123123123123123` would go into an infinite loop. Since factor.c currently operates on uintmax_t, we restrict the use of the assembly in longlong.h to when 'long' has the same width, to provide a more general guard for this code. * src/factor.c: Restrict the use of longlong.h assembly code, to when the width of intmax_t == long. * src/longlong.h: Remove the previous _LP64 guards to avoid divergence from GMP's longlong.h * NEWS: Adjust the info on build and runtime fixes.

Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2012-12-21factor: disable x86_64 assembly code for x32 buildsMike Frysinger
The current x86_64 asm code does not work for x32 (__ILP32__) ABIs, so disable it. Note simply deleting the q suffix is not enough. * src/longlong.h: Restrict x86_64 assembly to _LP64 targets, which is consistent with other checks in longlong.h and avoids this code on x32. * NEWS: Mention the build fix.
2012-12-04factor: fix infinite loop on 32 bit powerpcColin Watson
Both Debian and Ubuntu builds of coreutils 8.20 hang while running the test suite on powerpc, which is reproducible using 'factor 122'. This turns out to be somewhat related to http://bugs.gnu.org/12754, but not quite the same. uintmax_t is 64 bits, but the cntlzw instruction takes 32-bit operands, and the cntlzd option is only available on 64-bit hardware. * src/longlong.h: Add an _LP64 check around the PPC64 code, so that this falls back to the C implementations. * NEWS: Mention the fix.
2012-11-04build: avoid build failure on some HPPA systemsPádraig Brady
* src/longlong.h: Restrict some HPPA assembly variants to PA RISC V2.0. Note we also avoid this assembly for ilp32 runtimes, since even though the assembly is accepted there, it's not safe as the context can get clobbered between the 'add' and 'add,dc'. This fixes a compile failure with newer HPPA systems with default GCC CPU options. Reported by John David Anglin
2012-10-23build: avoid warnings about unused variables and macrosPádraig Brady
src/factor.c (__GMP_DECLSPEC): Move back from longlong.h to treat consistently with other stub macros. (__GMP_GNUC_PREREQ): Reference to avoid -Wunused-macros warning. (__GMP_DECLSPEC): Likewise. (ASSERT): Likewise. (__clz_tab): Likewise. (factor_using_division): Mark a variable as unused. (mulredc): Likewise. (mulredc2): Likewise. (divexact_21): Likewise.
2012-10-23build: avoid build failure on some sparc systemsPádraig Brady
* src/longlong.h: Restrict some sparc assembly variants to sparc V9. This was seen to be an issue with newer sparc systems with default gcc CPU options.
2012-10-04factor: merge with preexisting factor; integrate tests; avoid warningsJim Meyering
* src/factor.c: Renamed from factor-ng.c, with the following changes: Adjust copyright header to be consistent with others. Use xmalloc and xrealloc, to avoid segv upon OOM. Switch back to using readtokens to handle input. Diagnose invalid inputs. s/fprintf+exit/error/ (print_factors): Add comments. (strto2uintmax): Return strtol_error, not int. (read_item): Remove, no longer used. (main): Use atexit(close_stdout) so that we don't ignore failed write. * cfg.mk: Exempt src/longlong.h from several tests. Exempt run.sh from the test-list-consistency test. Exempt make-prime-list.c from numerous tests, since we won't be making it conform: it must not link with libcoreutils.a. Exempt factor-ng.c from the no-upper-case error message test. * AUTHORS (factor): Add Torbjörn and Niels. * tests/local.mk (factor_tests): Encode the 37 tests. ($(factor_tests)): Rule to generate a test script for each test. * tests/factor/run.sh: New script, marked as very expensive. * .gitignore: Ignore new generated files. * src/local.mk (src/primes.h): New rule. (noinst_PROGRAMS): Add make-prime-list. (noinst_HEADERS): Add longlong.h. Remove all wheel-related rules and files. * src/wheel-gen.pl: Remove file. maint: mark set-but-not-used variables with ATTRIBUTE_UNUSED * src/factor-ng.c (redcify, prime_p, isqrt2): Mark them, so we don't have to disable -Wunused-but-set-variable. maint: use __builtin_expect only if __GNUC__ * src/factor-ng.c (LIKELY, UNLIKELY) [__GNUC__]: Add #ifdef guard. build: avoid warning about unused macro * src/factor-ng.c (__GMP_DECLSPEC): Don't define here * src/longlong.h (__GMP_DECLSPEC): Define if not already defined.
